IMPROVED MACHINE FOR MAKING CUT NAILS.

The Schedule referred to in these Letters Patent and making part of the name.

To all whom it may concern:

Be it knownthat we, Jens lGosox Swnn'r, of Syracuse, in the county of Onondaga, in the State of New York, and J.BOYD Ennio'r'r, of the city, county, and State ofNew York, have invented a new and useful Improvement in Nail-\Ia'iehines; and we do hereby dcclare that the following is a full, clear, and. exact description thereof, which will-enable those skilled in the art to make and use the same, reference being had to the accompanying drawing, iorining partof this specification, in which drawing Figure 1 represents a plan or top View of this invontion.

Figure 2 is an end view of the same.

Figure 3 is a horizontal section of the same.

Figured is a lol'igitudinal vertical section of the same.

Figure 5 is a transverse vertical section of the same.

Figure 6 is a detached plan of the mechanism for locking and releasing the nail-plate;

Figure 7 is a face view of the nail-plate, showing the blanks, and also the finished nails.

Similar letters indicate corresponding parts.

This invention relates to ceitaiu improvements on a nail-machine, on which Letters Patent were granted to 'William A. Sweet, November 3, 1863, and which is so constructed that two blanks are cutfrom the nail-plato at each stroke of the punch.

Our improvements consist in a self-acting springelamp, which is pressed against the nail-plate, or the guide thereof, by a stud, rising from the punch, or fiom the head which 'carries said punch, and which is released automatically in such a manner that the nailplate is firmly clamped and held in position, while thepunch is in action, and that said nail-plate is released and free to be fed up as soon as the punch recedes; further, in the arrangement of fingers, acting in oppositedirections, in combination with the punch, in such a manner that the blanks, cutoff by'the action of said punch, are pushed outin opposite directions, and automatically delivered to the handing-mechanism; further, in the arrangement of grippers and headers, in combination with the fingers and punch, in such a manner that th" blanks, on being pushed by the fingers between the grippers, are firmly retained and exposed to the action of the headers, and, after the headers have receded, the finished nails are pushed out from between the grippers by the action of the succeeding blanks. A represents a frame, made of cast-iron, or any other suitable material, and of such a form' or shape that it will conveniently support the working-parts of our machine.

From the back end of this frame rises the standard .B, to the frontside of which. is hinged the feed or guide 0.

col'iveniontly fed through it to the punch 1), and with said lhed-clmunel we have combined a spring-clamp, E, from which-projects a wedge-shaped or inclined tappet, a, so that, as the punch advances, a stud, b, which risesfrom said punch, or from the head earlying the same, will strike the inclined edge of the tappot, and press the spring-clamp up against the nailplate, or against the teed-channel, and thereby the nailplate is firmly retained in position while the punch is in action.

in this locking-position the springrclamp is retained by a lever, c, which is provided with a nose, (Z, on one, and an inclined surface or cam, e, on its opposite edge, and the end of which passes through a slotin the loose end of the spring-clamp.

As the spring-clamp is pressed back by the action of the stud-Iron the tappet a, the end of the slot in the spring-clamp strikes the inclined surface 2 on the edge of the lover a, and thereby said lever is turned out in the direction of the arrow marked on it in fig. 6, and the nose (I is caused to catch over the outer edge of the slot in the spring-clamp, and said spring-clamp is retained in its locking-position. It is released again at the proper interval by a stud, f, coming in contact with an arm, g, which connects with the lever c.

The nail-plate is fed down until its lower end pro- I jects below the punch the width of one blank, a stop or gauge, j, being provided, w'hich prevents it dropping down beyond the desired point, and the punch acts in connection with two stationary cutter-st t, as fully described in the patentof William A. Sweet, heretofore mentioned.

As the punch advances, it cuts off from the nailplate, simultaneously, two blanks, one below the stationary cutter i and one below the stationary cutter i,

or between the two cutters t h As the punch recedes, the lower blank is sustained by 'a spring, '1', (see fig. 4,) which is secured to the toolstock or arm that carries the punch. \Vithout this spring, the blank would .be liable todrop off as soon as the punch recedes.

The blanks thus cutoff are exposed to the action of fingersjj, which move in suitable bearings ton the frame A, and to which a 1(-,(Jl1)1'0(3il:t-lllg motion is imparted in opposite directions by the action of a cam, 1;,

and elbow-levers l, (best seen in 2,) or by any other suitable mechanism. A

The bearings or boxes 1, which carry the fingers, are provided with springs s,.so that said fingers are not ri- 'gidly secured in the sun 10, but if one of saidfingers meets with an undue resistance, it is free to slide through its box, and injury to the mechanism is avoided.

One of the fingers forms the stops or gauge-which prevents the nail-plate dropping down beyond the desired point, and said fingers also serve to push the blanks out between-the grippers m m, the movable jaws of which are secured to a rock-shaft, n, to which .by headers H, which are secured to upright shafts, and

to which motion is imparted by the rod I, .which also serves to produce the reciprocating motion of the punch, and which acts on toes 1), projecting from the shafts, which carry the headers, or, if desired, any other suitable mechanism may be employed to produce the required motion of said headers.

' After the heads have been formed, the grippers open, and the finished nails are pushed out of the grippers by the succeeding blanks being pushed along by the action of the fingers j j.

The manner in which the blanks-are cut on from the nail-plate, will be readily understood by referring to fig. 7, which also shows the form of the finished nails.

' What we claim as new, and desire to secure byLetters Patent, is

1. The spring E, and inclined block a, in combination with the punch D and guide 0, constructed and operating substantially as and for the purpose described.

' 2. The locking-lever c, in combination with the spring E, inclined block a, punch D, and guide C, constructed and operating substantially as'and for the purpose set Iorth.

combination with the punch D and stationary cutters i i, colistruetedand operating substantially as and i'or the purpose set forth.

5. The grippers m m and headers H, in combination with the fingersjj, punch I), and stationary cutters i i, constructed and operating Hlll')Sl'-'l-llt-lftll as and for the purpose described.

6. The safety-boxes t, in combination with the fingers jj, punch 1), and cutters 'i i, constructed and operating substantially as and for the purpose set forth.

7. The combination, substantially as described, of the punchand cutters, (for cutting two nail-blanks at a time,)"with two sets of grippers and headers, for heading the two blanks so cut, so that each operation of the mechanism produces two headed nails.

Iii-testimony whereof, we have hereunto setour hands, this 28th day of February, A. D. 1867.
